SE, Yelm WA, 98567. The site is composed of two parcels numbered 64303400400 (parcel "A ") and 64303400501 (parcel "B "). The site is located north of State Route 507 and east of Creek Street. The proposed development will consist of 164 multi - family apartment units and 2 commercial buildings. The proposed project will connect gravity sanitary side sewers to STEP tanks with the effluent from these tanks pumped into a proposed pressure sewer main. The proposed 2 -3" force main will connect to an existing 4" main within Creek Street. (See Appendix A for Exhibit). The STEP systems were designed following the City of Yelm Development Guidelines (YDG) and the DOE "Criteria for Sewage Works Design ". Per the City of Yelm specifications, all STEP tanks shall provide 24 hours of storage volume in the tanks as well as a power transfer switch with an emergency generator plug in case of power outages. 2.0 S.T.E.P. TANK SIZING The sizing for the STEP Tank systems is in accordance with the City of Yelm Development Guidelines. According to the Washington State Department of Ecology "Criteria for Sewage Works Design" (herein known as DOE Manual in this document) C1- 10.1.6A, the tanks must include Detention Volume, Working Volume, and Storage Volume. Detention Volume is defined as the volume from the bottom of the tank to the lead pump 'off' position, or basically the wet pool volume of the tank. The required volume is 1.5 times the average daily flow for residential and 2 times the average daily flow for commercial. Working Volume is defined as the volume between the pump "on" and pump "off" position and shall be greater than the difference between the peak influent flow and the discharge of the STEP or grinder pump over 15 minutes (peak flow duration). In this case because the pumps required by the City are oversized, almost no working volume is required and the minimum of 6" between pumps "on" and "off" will be more than sufficient. See Appendix B for more information. Storage Volume is defined as the volume between the pump "off' and the top of the tank. It shall be equal to or greater than the average daily flow volume. 2.1 Commercial Buildings The commercial portion of this project consists of two buildings. The occupants of the building have yet to be determined and therefore it is conservatively assumed that half of each building will be restaurant and half will be office /retail space. For the restaurant portion, it is assumed that 60% of the space will be used for seating, with a seat density of 16sf /seat, and a customer count of 2 patrons /seat/day. Using these assumptions and Table 2 on page 7 -26 of the City of Yelm Development Guidelines (10 gpd /patron), and estimated daily flow can be set. For the office /retail portion, a demand of 15gpd /100 sf of building area has been used and is based off of Department of Health guidelines since the City's guidelines do not cover the office /retail situation. Please see Appendix B for calculations. 2.2 Apartment Buildings Below is a breakdown of the units, the number of bedrooms, assumed occupancy, and total number of occupants/ Unit Bed Assumed Occupaanc # of Units Total Occupants A 1 2 32 64 B 2 3 42 126 C 2 3 54 162 D 3 3.5 36 126 Total = 478 According to The City of Yelm Development Guidelines, Chapter 7, Table 2, the estimated daily sewer flow per resident for an apartment building is 65 gallons. See Appendix B for calculations. 2.3 Recreation Center and Office Building The recreational center /office contains two bathrooms with showers. The usage of this building is conservatively estimated to be the equivalent of two of the 3- bedroom units, or 7 people, giving a flow of 455 GPD. The recreation center /office will have its own STEP tank to handle this additional flow. See Appendix B. 2.4 Swimming Pool The project will contain a swimming pool for the apartment complex. A pool consultant has provided input on how pool cleanings and rainwater incursion is typically handled. The pool filter is typically cleaned once a week; a STEP tank dedicated to the pool will be provided to accommodate the approximately 2000 gallons that will be flushed from the pool during this procedure. A trench drain will be installed around the pool side. If rainwater fills up the pool to the extent that it overflows, the extra water will flow either into the landscaping or into the storm system. 3.0 Pumps According to 7F.020 -B.1 all STEP Tanks with a capacity of 3000 gal or more require the Orenco Model P20 05 11 pump or approved equal to be installed capable of delivering 20 gpm against a TDH of 105' and with a shutoff head of not less than 160'. The pumps must be installed in a duplex system. The working volume required is the volume from the pump OFF position to the pump ON position, and shall be greater than the difference between the peak influent flow and the discharge of the STEP over a period of time estimated to be the peak duration which is 15 minutes (DOE Manual C1- 10.1.2). See Appendix B for working volume calculations. The STEP system was analyzed using the PIPE -FLO hydraulic analysis program. This program is used for analyzing pressurized piping networks, including force main systems. For the analysis, the STEP system was divided up into zones (see Zone Map in Appendix D). There are six pumps in Zone 1, nine in Zone 2, and two in Zone 4. The probability method was used as guideline to estimate the number of pumps expected to be running at one time. This method specifies the number of pumps operating simultaneously based on the total number of pumps in the zone. See table below: # of Simultaneous Zone # Pumps Operations 1 6 3 2 9 4* 3 0 - -- 4 2 2 5 0 - -- * The number of simultaneous pump operations in Zone 2 was conservatively increased from 3 to 4 since there are nine pumps in this zone. In the PIPE -FLO model, each of the operating pumps was assumed to be running at the peak flow rate for the building (see Appendix B). The pumps selected to be operating simultaneously were the ones with the highest peak flows in the zone. See Appendix D for the complete analysis. 4.0 SEWER LINES Gravity side sewers convey flow from the cleanout to the STEP Tank. Service lines convey flow to the force main. The force main then conveys the effluent off the site. 4.1 Gravity Side Sewer The side sewer pipe sizes will be 6" per the standards. 4.2 Service Lines The service lines will be 2" in diameter. 4.3 Force Sewer Main Creek Street has an existing 4" pressure main. The proposed onsite main will be 2" or 3" in diameter (see construction plans). 5.0 GREASE INTERCEPTORS Since the occupancy of the commercial buildings is not known at this time, grease interceptors have not been specified. The gravity side sewers for the commercial buildings have been laid out in a manifold configuration, with each building space having its own side sewer stub (please refer sheet C19 of the construction plans). When the occupancy types have been determined, grease interceptors can be placed along the gravity side sewer lines for the appropriate commercial units, upstream of the STEP tanks.

We u Omnco Sysioins', Inc. Pnge 3 of 6 Wng a Pump (fume A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flaw (gpm or Usec) and pressure (total clynamic head, or TDH), providing a graphical representation of a pump's optimal performance range. Pumps perform best at their nominal /low rate —the value, measured in gpm (or Uses), expressed by the first two numerals in an Orenco pump nomenclature. At low flow rates, TDII varies from pump to pump, so it is represented as a dashed line in the pump curves.

System Analysis Project: Creek Road Mixed Use Project number: 07118.10 Subject: STEP System Analysis By: JAB /KMB This appendix contains the STEP System Analysis performed using the PIPE -FLO program. For this analysis, the Hazen - Williams method was selected for calculating the pipeline friction losses. A C value of 150 was assumed. For the pressure at the connection to the main in Creek Road, 30 psi was assumed (per Randy Hatch, Yelm Sewer Department). The following items are included: Page 1 - Sanitary Zone Map Page 2 - PIPE -FLO system schematic with the zones outlined. Calculated results are also shown. Page 3 - 5 - PIPE -FLO list report. Results are shown for the force main pipelines on page 4 (note that all velocities are under 8 fps). Page 5 lists the results for the operating pumps. Page 6 - Graph of the Orenco PF200511 pump, showing the head curve for both one and two pumps running. Note that the curves shown will meet the required pump operating points listed on page 5. 7- oA ss ss N n tj ry L LLJ LU uj cr LU LU s i ss Co 31 -S - - - - - S F-I LF) 6MPdVV4 3NOZ ),dViINVS 9LtO\0 X!Pu8ddV\IJOdQa d31S\OL9LtL0\6u!JaOU!6u3 punoS\:N WOL94 OLOZ '60 uOr g v s 30 �ti �= s u o g 3z og' A Ell System: step system 01/09/10 1:17 am Lineup: Peak flow - not all pumps on rev: 01/09/10 1:12 am Company: Sound Engineering, Inc.
